Peterson, the president of Central Council of Tlingit and Haida Indian Tribes of America, immediately told the crowd of more than 300 people to bear with him as he shared his frank, straightforward thoughts on the first officially recognized Indigenous Peoples Day in Alaska.

“This is not an insult to those who are not indigenous,” Peterson said, “but this is recognizing the people whose land that you’re standing upon, people who have paid the ultimate sacrifice. People who have lost their land, their culture, traditions.”

Gov. Bill Walker, who was in attendance Monday, issued a proclamation in 2015 that made Alaska the first state to rename the second Monday in October as Indigenous Peoples Day instead of Columbus Day. Since 1937, Columbus Day has been a federal holiday honoring the Italian explorer who landed in the Caribbean in 1492.
